Abstract
In an approach for protecting against use of clones of electronic devices, a first sequence value is initialized on the server and an equal second sequence value is initialized on an electronic device. In response to a first login request to the server from a user operating the electronic device, the first and second sequence values are compared. If the values are equal, processing of the login process continues. Otherwise, the login request is rejected. If the login is successful, a next value is computed for the first and second sequence values, and the next first and second sequence values are stored on the server and on the electronic device, respectively.
